Glassfibre resin polymer (GFRP) bolting system is a comprehensive rock bolting system with various components that include a plastic nut, GFRP nut, steel nut, plastic plate, GFRP plate, couplings, adapter and injection connection. Available as solid and hollow bolts
The bolt has a high ultimate load and due to its profile, offers a maximum bond strength with all grouting materials. The bolt has a continuous thread and can be trimmed if required.
Solid bolts can be installed with cement grout or Lokset® resin capsules, while the installation of the hollow rods can be carried out with cement grouts or injection resins.
Continuously threaded, high strength rock bolting solution. Developed for strata support in mining and tunnelling, it has proven to be a versatile product for many applications. The GFRP system allows the bolts to be cut to length as required on location, as well as protecting equipment and machinery of they are required to be mined through. Due to it's high corrosion resistance, it is perfectly suited for long term and temporary ground support.

Glassfibre resin polymer (GFRP) mesh provides surface support coverage to loose rocks between installed bolts. Suitable for temporary and permanent solutions. Low-weight, ideal for decreasing risks associated with manual handling.
This mesh complies with standard grid applications while providing the added benefits of durability and cuttability. The high load capacity at each joint, comparable to welded steel mesh, is unique and makes the design of GFRP grid reinforced RC structures a viable option. Available in a range of sizes to suit individual application.
Australia's only long life resin capsule offering 12 month shelf life. Improved efficiency & reduced storage, waste and disposal. This new resin offers 12 month shelf life with significantly enhanced storage abilities in both hot and cold conditions. A further reduction in resin volume will ensure cost reductions in freight, storage and waste.
The Lokset Advance resin capsule consists of a reinforced, thixotropic polyester resin mastic in one compartment and an organic peroxide catalyst separated by a physical barrier in the other. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components causing a chemical reaction and transforming the resin mastic into a solid anchor.
